IPatentd Aug. 3, 1909.

Application filed December 23, 190,8. Serial No. 468,900.

Bo it known thatl, LA VnnNn W. NOYES, a citizen of the United States, residing at Chihago, in the county of (look, in the State of Illinois, have invented certain new and useful Improvements in Engines, which are oi particular use in connection with internal-comlnistion engines, commonly known as gas-engines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereoi'l, which form a partof this specification.

My invention relates more particularly to those engines employing cooling jackets for the engine cylinders, which cylinders, in the highly heated as a consequence of the com- .bust ion of explosivemixtures, unless effect "ive means are employed to cool the'cylinders.

The object of my invention is to provide improved means for rapidly dissipating, or removing, from the. cooling liquid in the jacket, the heat absorbed by the liquid from the engine cylinders, whereby the quantity,

and hence the weight, of the cooling liquid iecessary to maintain the cylinders at proper and safe working temperatures, is reduced. The cooling liquid which it preferably em; ploy is water, because of its effectiveness and cheapness.

My invention may generally be described as comprising an engine having an operating cylinder provided with a liquid-containing jacket and an overlying radiator projecting upwardly from said jacket which lies beneath the radiator and having a main liassage extending longitudinally of the radiator upwardly from the jacket, and which main passage coinn'iunicates with the interior of the jacket, the wall of said I radiator being formed in convolutions that Fig. 1. Fig. 5 is an elevation of the radiator shown in Figs. 1. to 4, inclusive, as made of sheet metal. Fig. 6 is a top plan view of the radiator shown in Fig. 5. Fig. 7 is. a vertical section of the radiator as made of cast metal. Fig. 8 is a top plan view oi the structure shown in F i v 7.

Like parts are indicated by similar characters of reference throughout the different figures.

The engine cylinder C is surrounded by a water acket 5 which a relatively large opening 9" above the cylinder. jacket flange 5 surrounds the outlet open 111g 9, to, wh ch flange is secured a flange 3 that is provided with an inlet 9 and an upwardly extendin tapering riser por:

tion (5 having an in ct openlng 9 and whose upper end 6*? is threaded, the open ings 9 and 9 communicating with the relatively large opening 9". A second'riser or pipe portion 7, is screwed into the threaded part 6} of riser portion 6. Surrounding this pipe '2' and, suitably secured to the flange 3, is a water receptacle 8, projecting upwardly from said jacket which lies heneath said receptacle, said receptacle having a main central; passage extending longitudinally of the receptacle upwardly from the jacket, and which main passage 'con 1n1unicates-with the interior of the jacket. The wall of the receptacle 8 is formed in convolutions to constitute said reflfiptacle a radiator, said convolutions defining supplemental passages communicating with the main passage and also extending longitudinally of the radiator upwardly from the jacket. As shown, the convolutions form radial, vertically extending, hollow wings, or troughs, W, the supplemental passages or hollows 1 of these wings communicating with the said main passage, and, in fact, forming extensions or it, said main and su )plcniental passages forming extensions of the jacketed water space surrounding the cylinder. Between the wings arevertical air-passage ways 2. A deflector 4, whose purpose will appear, forms a continuation of the partition between the openings 9 and 9 and extends downwardly into the jacket.

The water surrounding those portions of the cylinder in which the combustion takes place, becoming heated, rises throu h the inlet 9 to replace the relatively coo er water, particularly the water contained in the hollow wings, the water rising and descending as indicated in part by the'arrows. The rising heated water flows through the riser 6, 7, and the descendin cooled water flows" is especially pronounced when the engine is portable.

The rising heated water will flow through the top of the riser 6, '7 and-also through the I perforations 12, that are preferably formed 1n the riser along its length, the heated water, after passing from the riser, finding its way into the hollow wings, where it becomes cooled olf rapidly because of. the

large area of heat conducting and radiating surface afforded by these wings. The perfo rations p in the riser portion 7 serve to permit theheated water to escape from the riser under circumstances where the water would not he papable of esca ing through the top of the riser, as when the water becomes reduced in volume, owin to evaporation and leakage. As the meta? forming the sides of those wings becomes heated by the water, the air in the air-passage ways between the wings and upon the exterior of the radiator, will become heated and rise, being replaced by cooler air. A continuous flow of air between the wings W is thus established, rapidly carrying away the heat imparted to the wings by the watler. Thusv the water becomes rapidly cooled, the cooled water flow- IIIgClOWIlWZLId into the jacket 5, again to absorb heat from thecylinder to cool the cylinder. Because of the rapid coolingof the water by reason of the large area of conductin and radiating surface aiiorded by the hol ow wings W, and the induced. cum 1 rents of eoolin air between the wings, which rapidly a sorb and conduct the heat away, the circulation of the cooling water 5 will be very rapid, enabling the cylinder to be cooled to a proper and safe working temperature with a small quantity of water.

I prefer to make the winged part of the radiator of'sheet metal, tapering downwardly, as shown in Figs. 1, 2,3, l, 5 and 6', as the best results are thereby'secured. If

desired, the radiator may be cast as shown",
